a To all "whom. it may concern Be it known that 1,.RANDALL B. ANDRos, a citizen of the United States, and a resident of Portland, in the county of Cumberland and State of Maine, have made certain new and useful Improvements in Sheet-Music Turners, of which the following is a specification. 1

My invention is an improvement in sheet music turners and the invention'hasfor its object to providemechanism' of the charac tersp'ecified having means for supporting sheet music and having means for engaging the individual leaves and for turning said leaves in succession from one side, to the other, the said means being capable of operation by the musician, and wherein the leaves may be turned from'either side.

In the drawings: Figure 1 is a front View of the improved turner, Figs. 2, 3,4 and 5 are sections on the line 22, 3r3, l4 and 5-5 respectively of Fig. 1, each looking in the direction of the arrows adjacent to the line, Fig. 6 is a perspective view of one of the leaf turning arms, Fig.7 is a section on the line 7'7 of Fig. 5, looking in the direction of the arrows adjacent the line, and Fig. 8 is asectional'viewof a modified construction.

The present embodiment of the inventior.

comprises a support consisting of a base plate '1, which has its upper surface grooved or concave longitudinally as indicated at 2- to receive the lower edge of thesheet music or folio, and a back support-is provided against which the rear face of the sheet or folio rests. This back support, in the present instance, is a frame 3- composed of wire bent into ornamental figures, the several figures being connected as shown by wirc.

wrappings 4. The frame is adjustably connected to the base'by means of loops, each loop consisting of a front member 5 which is slidable through a bearing 6 on the rear side edgeof the base 1, a rear member 7 which is connected to the frame, and a hottom connecting portion 8, the said portion 8 being U-shaped and having one end connected to the portion 5 and the other to-the portion 7. The portion 7 is connected to the frame by bending the said portion around I the frame, as'shown in Figs. 1, 2 and 3', and

the frame may be adjusted Vertically'with respect to the base by means of the bearlngs .6 before mentioned.

Set screws 9 are threaded through the base from the front to the rear, and the set screws engage the portions 5 of the connecting loops to secure the frame in adjusted posltlon with respect to the base.

A shaft 10 is journaled vertically with respect to the frame and the base, the shaft being at the center'of the base and in rear thereof and the shaft is'held rigidly in loops llformed in the central figure composing th frame 3, and in bearings 12, 13, 14 and 15 connected to the frame, the said bearings being rings of wood or the like connected to the frame in any suitable manner, and all'the bearings are in alinement.

I An ornamental cap or head 17 is connected with the top of the shaft 10, the cap or head having an opening at one end engaged by the threaded end of the shaft, as shown in Fig. 2. Each of the turning arms 18 has connected with one end thereof a sleeve or hub 19, the sleeve of each arm having a central opening for engaging the shaft 10. At the other end each arm has an angular depending arm 20 to which is rigidly connected a spring operated clamp 21 for engaging a leaf of the sheet music or of the folio. In the present instance three arms 18 are provided and the arms are arranged on the shaft one above the, other between the bearings 13 and 14, and they are held in position on the shaft by the said bearings.

A worm or screw 22 is arranged on the shaft between the bearings 14 and the cap 17 and the said screw or worm is in the form-pf a sleeve having a spiral groove, as

Arms27 extend upwardly from a collar 28 which is.mounted to slide on the shaft 10 above the bearing or stop 12 before mentioned and a coil spring 29 is arranged between the collar and the bearing or stop,

the spring normally acting to force the collar upward. Each of the arms 27 is connected rigidly at its lower end to the collar 28, and at its upper end each arm has an eye 30 engaging over the adjacent arm 2- It will be evident that when the collar 28 is moved downwardly the nut 23 will also be moved downwardly, and the collar is' 33, connected to the lower end of the shaft 10 and the said lower ends of the shaft and link are bent at'an obtuse angle to the body portions thereof, as shown at 10 and respectively. The link and the shaft are parallel throughout their course, and each of the turning arms 18 is limited in its swinging movement to approximately an arc of 180 by means of transverse stop and release rods which are arranged behind the shaft 10 and are. supported by the frame/ The stop rods 3%, three in number in the present instance, are arranged o-.-.e shove the other and normally stand just below the body portion of the adjacent arm. he rods are of spring wire and are attached rigidly at their ends to the frame. Each rod is engaged by an eye 35 connected with an operating link to be'later described. The eyes 35 engage the rods near their centers and at their ends, the rods are rigidly secured to vertical braces or struts 36 forming a part of the frame 3 before mentioned. coil spring 37 encircles each rod near one end, and each rod has a head 38 at the end. The springs are fixed at the end acent to. the head and from the opposite end of each spring a flexible member 39 extends around the collar or huh 19 of the adjacent arm 18 to a. connection with the said arm, indicated at 46.

It will be noted that each of the sleeves or hubs 19 of the turning arms is peripheral grooved, as shown. at ll, to receive tl lole member, and each :tlexilole nnnnher p" i almost entirely around. the huh or co when the turning arm is at the r: t stand. When the turning arms right of the music stand, as shown in .11 1, the spring 37- is under tension and the said spring tends normally to swing the arm to the left. Each turning arm is normally held at the right of the stand by means of a latch 42 rigidly fastened to the adjacent rod 84, and extending forwardly from the rod into engagement with the turning arm.

Each of the latches, as shown in has alug engaging in front of the a restrain the action of the spring Will be evident that until the latch. leased the arm cannot be turned. latches are released in succession by spring ing the central port? of the rod which sum-sorts the latch do wardly by means of lin iii--13. Each link consists of a lower sect. on &3, having eyes l lmounted to slide on. theshaft 10, and an upper section 43 having eyes 4A also sliding on the shaft. The adjacent eyes of the sections are rigidly connected to constrain the sections to move together when the links are moved downwa llyr Each oi; the sections 43 has angle po at its ends which carry the eyes 44-, and each of the sections 43 has similar angle portions at its ends which carry the eyes 44.

T he links are arranged well in rear of the shaft 10 and the frame 3 and the angle portions extend forwardly beyond the links 31 the sliding connection with the shaft 10. A handle is connected with the lower end of the iowersection of each link, each of the hen ll having an'eye rigidly connected to the a cent eyehe link. By means of tl the may be moved 11L latches that hold to the right it is engaged with the t latch to hold the arm from turn- 0 the left under the influence of the tl'ierewith. As the arms 13 are moved s, and after the ady for oper- 'n the first is pressed serving as ing ari s. o pressed arm is a? of h the clamp 2.1 synngto the send. leaf has "indle 15 is cond turnis' released in. arms and 1 may he r nd for repeat returning of the screw in connected. consisting of ally iron" the spending in int i arniis swing this d ii-ending turning arms c stand they 5 lepressing 3l. when a xile pressed downi 'i may oe- I F's 1 the nnge; u I this sage l. O (l ward the nut 23 is moved longitudinally of the screw 22and the screw is rotated toward the right of the stand, swinging the angle arm 46-47 and swinging all of the turning arms to the right of the stand. Vhen the arms have been swung to the right the latches 42 are depressed and the music is ready for a repeat.

The lmproved music leaf turner is of simple construction, and it is also simple in the latch to the engaging position. The imthe number of'arms that might be operated proved stand is of light weight, and may be arranged on the stand of a piano or on a music stand of any construction. While but three turning'arms are shown, -it is obvious that there is no limit except convenience to in the same manner. The arms' are not de pendent upon each other, and each arm moves independently of all the other arms.

It will be understood that the rods 34 may be. secured to the braces 36 in any desired manner. In Fig. 8 is shown a modified construction of spring for operating the turning arms. In this construction the arms 18, but one of which is shown, and corresponding to the arms 18 of the construction just described, have hubs 19 journaled on the shaft 10. The upper face of each hub is provided with an axial depression 50, and a coil spring 51 encircles the shaft 10 at each hub. .The lower end of the spring 51 is received in the depression 50 and one end of the spring passes through aradial opening 52 leading from the depression to the periphery of the hub. This end of the spring is secured to the hub in any suitable manner as indicated at 53, while theother end of the spring is secured to the shaft as indicated at 54. The operation precisely the same, as with the turning arm just described. v
